COTTON HARVESTER.

SPECIFICATION forming part of Letters Patent No. 319,710, dated June 9, 1885.

Application filed April To aZZ 1071 0111, it concern.-

Be it known that I, DANiEL l3. HAsELToN, a citizen of the United States, residing at Charleston, in the county of Charleston and State of South Carolina, have invented certain new and useful Improvements in Cotton-Harvesters, of which the following is a specification, reference being had therein to the accompanying drawmgs.

My invention has relation to cotton -harvesters, and its object is to provide a machine that will be drawn by horse through the field and gather the ripe cotton from the plants; and to that end the novelty consists in the construction, combination, and arrangement of parts, as will be hereinafter more fully described, and particularly pointed out in the claims.

In the accompanying drawings the same letters of reference indicate the same parts of the invention.

Figure 1 represents a side elevation of my improved cotton-harvester. elevation of the machine, partly in section. Fig. 3 is a side view of one of the adjustable side guards. Fig. 4. is a cross-section on the line as m, Fig. 2. Fig. 5 is a cross-section on the line 1 y Fig. 2. Fig. 6 is a bottom plan view of the stationary friction driving-plates. Fig. 7 is a vertical cross-section of the same as they appear on the driving-shafts. Fig. 8 is a cross-section on the line z z of Fig. 7.

A A A is the frame-work of the'machine.

B B are the draw-bars upon which the frame rests, and each of said draw-bars extends from the axle G to the plate D, which is rigid with the forward end of the draw-bar.

E is the connecting-bar, which extends upward and forward, and is connected to one of the thills F. This thill has a rigid plate, G, and by means of the pin 9 the thill'may be rigidly adjusted with reference to the bar E. So, also, the lower end of the bar E may be adjusted by means of the pin 01 and plate D to correspond to the position of the thills.

The axle O is journaled in bearings in the rear ends of the draw-bars B, and said axle is provided with a pair of carrying-wheels, one of which is shown in Fig. 1, and upon these wheels the machine rests.

Fig. 2 is a front I is the elevator-box, and K is the elevatorbelt, mounted upon the rollers 15 i. L is a pulley, around which a belt passes from a pulley (not shown) on the axle O, which belt passes under the roller 2', so as to give the elevatorbelt K the proper motion, as indicated by the k ing across the top of the front end of the machine. The outer end of this shaft R is pro vided with a chain-pulley, S, around which passes an endless chain, T, which passes over the adjustable guide-pulleys t t, and around the pulley M. It will thus be observed that as the machine moves forward the endless chain gives motion to the shaft R, and it in turn gives motion to the shafts N N, from the front outward that is, as the machine travels forward between two rows of cotton -plants the right-hand shaft, N, turns to the right and the left-hand one, N, turns to the left.

2 is the top rail, 3 the bottom rail, and 4 'a vertical tie or brace, which together form a frame sliding upon the shafts N N.

5 is a regulatingscrew, by means of which the said frame may be raised, lowered, or held in any desired position.

6 is a cap upon the upper end of the tube 8, which fits over the shaft N or N, and the outside of the upper part, 7, of said cap 6 is journaled in the bearing 8 on thetop rail, 2, while the inside of the part 7 of said cap is hexagonal to correspond to the shaft N or N. This construction allows the shaft to drive the tube 8, and the tubes being journaled in the rails 2 and 3, so as to be raised or lowered,it follows that the tubes may be rotated with equal facility in any position in which they may be adjusted.

Upon the tube 8 are mounted collars 9,each

spindle is mounted, so as to revolve freely, a tube,;14, to which are secured the toothed picker-cylinders 15, while to the inner end of said tube is secured a convex-faced friction-roller, 16.

17, is a friction driving-plate, having a central "perforated base, 18, through which the tube 8 passes, so as to rotate freely therein. The under side of this plate is provided with a rubber track, 19, secured in place by clips 20. This track extends about two-thirds of the distance around said plate, so that the roller 16 is operated so as to revolve the picker-cylinder only while it is in contact with the track, and in the space between the ends of the track 19, the roller not being operated,- the cylinder is left free upon the spindle.

From this construction it will be seen that the collar 9,being secured to the tube '8,which is driven by the hexagonal shaft inclosed therein, is rotated therewith, and consequently nected b'ya yoke, all are kept uniformand rest the spindles radiating from said collar are r0 tated in a plane at right angles to the axis of said tube 8, and,t-he picker-cylinders 15 being loosely mounted 'on said spindles, when the friction-rollers 16 are in contact with the rubtrack the said cylinders are rotated upon their own axes in addition to their common myomticn about the axis of their shaft N. v The plates 17 are constructed in pairs, and those in each pair are connected by a yoke, {21, secured to said plates by perforated lugs men the latter passing through corresponding slots in the yoke and held in place by a split spnng-key,"23, so that if the key be withdrawn the parts may be separated.

Each driving-plate 17 has a radial slot, 24,

in width corresponding to the tube 8, and 25 I is a corresponding section of the plate, which fits into the slot 24, so that when it is in place The section 255s secured by rivets 26 to the yoke the plate presents an unbroken surface.

21. If it becomes "necessary to remove the plate 17,the key 23 is removed and the plate withdrawn from the coupling-yoke.

Upon the face of the plate 17, underneath the rubber track, is aconcave groove, 27, corresponding in form to the face of the roller 16. "This allows the rubber to conform more even 28 is a depending flange extending around the plate 17,which prevents the roller 16 slipping cutwardly, should there be any tendency to do so. Each pair of the plates 17 being conevenly by gravity upon the rollers 16, and consequently a very regular operation of the-pickslots 29 30 in said arms, whereby they may be The extremity of laterally moved in or out.

each arm has a perforated boss, 32, through Free a'c cess may then be had to the spindles and pickl comparatively small and limited in its dimen- 30'are two arms, adj ustabl y secured tothe l plants, and the picking-cylinders extend into them on each side, while the side guards, 35, pass on the opposite sides of the plants and prevent them from springing away from the cylinders. As the branches of the plants are released by the cylinders they are prevented from being damaged by the sides or forward end of the elevator-box andby the rollers 36, which are loosely mounted in the frame in the rear of the picker-cylinders.

After the picker cylinders have gathered the ripe cotton and carried itinside the frame, the fiber is removed from the teeth of the cylinders in any suitable manner, and it falls upon the elevator-belt, whence it iscarried upward and discharged into the bag 37, securedtothe rear platform, 38. In some cases it may be desirable to dispense with the bag and secure a sheet to the platform, so that when full its four corners may be gathered up, tied, and the bundle removed, and a new one placed in position.

A very important fea-tureof myl inachine is inclining the shafts N N forward, because this position allows the lower series of pickercylinders to reach under the lowest branches of the plant, even though they be bent to touch the ground, and then gently lift them, so as to have access to all parts thereof. After the first blow is picked the picker-cylinders are roo raised by means of the regulating-screw 5 and Y the middle blow harvested. The pickers may then be farther elevated, or the forwardpart of the whole machine elevated by means of the plates 1) and G, so as to bring the picker-cyl-' inders in line with the last or top blow,which is harvested with equal facility. By these means of adjusting the pickers a very wide field of adjustment is obtained with a machine sions, and it will also be observed that no part of the plant is operated upon except that ortion which is in full blow and ready for arvesting. V In the present case I have not particularly described the construction of the picker-cylinders or the means of removing the picked cotton therefrom, as they are the subject-matter of another application-to wit, Serial N 0. 112,290, filed November 20, 1883.

Having thus fully described my invention, what I'claim as new and useful, and desire to secure by Letters Patent of the United States, is-

stems independently mounted upon radially- Ip'rojecting "spindles attached to a forwardlyinclined shaft, in combination with mechanism, substantially as described, whereby said 1. In a cotton-harvester, a series of pickerpicker-stems will be operated by the forward motion of the machine, as and for the purpose set forth.

2. In a cotton-harvester, the combination of 5 an inclined rotating shaft, a series of revolving pickers independently mounted on radially-projecting spindles on and rotating with said shaft in their own plane, and means, substantially as described, whereby said picker- IO stems may be raised or lowered, as and for the purpose set forth.

3. In a cotton-harvester, a series of pickercylinders radially mounted upon a forwardlyinclined shaft journaled in the frame, in combination with means, substantially as described, whereby the inclination of the shaft and frame may be varied, as set forth. 4.
